Abstract
Abstract:
Hot water is an important component in the recovery or extraction of bitumen and heavy oils. This hot water tends to form emulsions with the oil and when these emulsions are broken by demulsifiers and the oil separates, the remain-ing water retains a black color and cannot be recycled in the process. The black color has been most difficult to remove, but it has now been found that it can quite easily be removed by certain selected adsorbents. These include high ash coal rejects, fly ash from coking gas and red mud.

i .1 I, Clarification of Black Water Produced urea g Recovery of Bitumens and heavy Oils This invention relates Jo a process fox the clarify , cation ox black water produced during the recovery or : extraction of bitumen or heavy oil.
Vast reserves of bitumen and heavy oils are Jo be found in Western Canada and hot water is an important component in the recovery or extraction of these materials The hot water tends to form emulsions with the oil and when these ,` emulsions are broken by emulsifiers and the oil separated the remaining water retains a black color and cannot be I 10 recycled in the process Furthermore, this black waxer is not considered to be an environmentally safe material for disposal.
Attempts to clarify this black water have not been successful in the past. For instance, filtering, extra-lion and centrifuging techniques have been attempted.
Canadian Patent 878,656 describes the use of petroleum coke fox repaving oil from processing water but petroleum coke has not been wound to be successful in clarifying this black water Canadian Patent 979,81~ describes the use of bituminous coal, lignite coal or brown coal or clarifying waste waters, but again these materials have not been found to be useful for clarifying the black water Canadian Patent 706~714 describes the use of fly ash from bark, pine cones and pine needles for removing color bodies from a fluid and that patent indicated that coal fly ash was not a suitable material for removing color bodies. Another material that was tried without success was active carbon, which left very turbid water ',, Jo `, It is the object of the present invention to find an Jo inexpensive adsorbent for the coloring matter found in the black water In accordance with the present invention it has sun-S praisingly been found that the black water can be clarified ' by contacting it with a variety of high ash materials or -', red mud. The high ash materials include high ash coal, high ash coal rejects and fly ash from coking gas. The red mud, high ash coal rejects and fly ash from coking gas were found to be the most effective materials and they I' functioned best in the form of a fine dust or powder.
Typically, the particle sizes are less than 100 mesh ' Canada Standard Sieve).
; Red mud is a residue which occurs when bauxite is disk solved in caustic soda at high temperatures to produce alumina as a raw material for the electrolyte production of aluminum. The red mud in dry form has a quite large surface area and its composition varies quite widely depending on the type of bauxite from which it originates.
The effectiveness of these particular materials was clearly not expected, particularly in view of the poor results obtained with coal fly ash in Canadian Patent 706,714.
One method of contacting the adsorbent with the black water is to retain the adsorbent as a filter bed in an extraction column. The black water is then flowed through j the column in an upward or downward direction.
The black water is contacted with the adsorbent until the water is colorless. Depending on the contact time required, a plurality of columns may be arranged in series as a continuous flow system or a batch quantity of black water may be recycled through a column or columns until the water is colorless.
The preferred adsorbent according to this invention are all very cheap materials and are in fact, largely industrial waste materials. As a consequence, when they ~3~3~
are no longer effective as black water adsorbent they can be dumped as waste material , This invention can more easily be understood from a j study of the following examples.
example 1 . Black Water Samples Three black water samples were obtained for this investigation, water Sample A being obtained from in situ recovery of bitumen, water Sample B being obtained from in situ recovery of heavy oil and water sample C being a formation water sample from the field operation ox Texas Gulf, at North Battle ford, Saskatchewan.
B. Sorbent Materials Five different useful sorbent materials were Mint coal : 15 rejects, Mint coal, Lignite ash and Great Canadian Oil Sands fly ash and red mud.

This water was pumped upwardly through a stainless steel column 30 cm long and 0.6 cm in diameter 20 packed with 5 grams of solid sorbent. The water effluent from the phylum was recycled to the separator funnel unit it became colorless.
